ATTACHMENT FOR CORNETS AND OTHER BRASS INSTRUMENTS.

Specification of Letters Patent. PatentedApr; 22, 1919- Applicationfiled December 30, 1918. Serial No. 268,896.

To all whom it may concern:

- Be it known that} I, CARL'J. MAGIN, a citiadapted to be used forchanging the tone of a cornet or .other similarmusical instrumentof thekind generally referred to as brass instruments, without materiallydiminishing the'volume =of"the 'sound produced by the instrument.

Themain'object of-my invention is to provide a device for making acornet or other musical instrument sound substantially like a saxophone.

Another object is to provide a saxophone attachment for musicalinstruments of the character commonly known as brass instruments; thatis compact, inexpensive to -manufacture and easy to apply to or removefrom the instrument with which it is used.

Figure 1 of the drawings is a side elevational view of a cornet equippedwith a device constructed in accordance with my invention.

Fig. 2 is an enlarged longitudinal sectional view of said device; and

Figs. 3 and 4: are cross-sectional views, taken on the lines 3-3 and H,respectively, of Fig. 2.

My improved device consists of a member that is adapted to be arrangedin front of the bell of the instrument on which the device is used andconstructed in such a manner that it will convert the natural tone ofthe'instrument into a relatively deep tone, and means for sustainingsaid member in operative position on the instrument.

In the form of my invention herein shown the device consists of arelatively long hollow, cone-shaped member A closed at one end andarranged with its opposite end presented toward the bell 1 of theinstrument,

and a su' porting means B for said member that projects into the bell ofthe instrument, as shown in Fig. 2. I prefer to support the member A onthe instrument by means or a substantially frusto-conical-shaped memberB of slightly smaller diameter than the member A, arranged oppositely tosaid'member A and having its large end connected to the large end of themember A in such a manner that the sound waves which enter the member 13can pass into the member A. In the form of my invention herein shown thelarge end of the member B is partially telescoped within the large-endof the member A and permanently connected to same, but this is notessential to the successful operation of my ,device. The supporting:member B is open at its small end or inner end and is provided withmeans for connecting said member to the bell 1 of the instrument andholding it spaced awaylfromthe' bell sufiiciently to permitsomeof-thesou-ndproduced by the instrument to escape through apassageway lying betweenthe belland' the supporting member B. In theform of my invention herein shown the supporting member B is provided atits inner end with a plurality of lugs or ribs 2 that bear snuglyagainst the contracted portion of the bell of the instrument, and thushold the member B securely in position and spaced far enough away fromthe bell to provide a passageway through which some of the sound canescape, the lugs or ribs preferably, but not necessarily, being formedof cork or other material that has some resiliency, as such an attachingmeans holds the supporting member securely in position and permits thedevice to be easily applied to or removed from the instrument.

I The supporting member B is so constructcd that it will not materiallyinterfere with the sound waves passing into and out of the member A, andwhile said supporting mem ber can be constructed in various ways toaccomplish this result, I prefer to provide the member B with one ormore slots or openings 3 that extend longitudinally of said member froma point in proximity to the inner end of same to a point in proximity tothe outer end of said member which is joined to the member A.

A device of the construction above described, when arranged in operativeposition on a cornet, trombone, baritone horn, French horn, alto born,or any of the other musical instruments of the kind commonly known asbrass instruments, will make the instrument sound substantially like asaxophone, due to the fact that the hollow cone-shaped member A isarranged in such a position with relation to the bell of the instrumentthat it will convert the natural tone of the instrument into arelatively-deep tone. The. device is small and compact enough to enableit to be carried conveniently in a coat pocket; it can be applied to. orremoved fromithe instrument easily and it is of such simple design andconstruction th at it can be manufactured and sold at a low cost.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. A device for changing the tone of musical instruments of thecharacter-referred to, comprising a relatively long, hollow, coneshapedmember, closed at its apex, an oppositely-disposed,frusto-conical-shaped member, open at both ends and having its large endconnected to the large end of said coneshapedmember so as to cause thesound waves which enter said frusto-conicalshaped member to pass intosaid cone-shaped member, said frusto-conical-shaped member being'adaptedto be inserted in the bell of the instrument, and openings in the sidesof said frusto-conical-shaped member; for the purpose described.

A device for changing the tone of musical instruments of the characterreferred to, consisting of a hollow member of substantially cone shapewhose large end is open, a frusto-conical-shaped member arranged withits large end pro ecting intothe open end of said cone-shaped member andconnected to same, lugs on the outer end of saidfrustoconical-shapedmember that are adapted to be forced into'the contracted portion of thebell of the instrument, and elongated slots in the sides of saidfrusto-conical-shaped member located between said lugs'and the pointwhere said member is attached to the coneshaped member. i

3. A device for changing the tone of musical instruments of thecharacter referred to consisting of a relatively long, hollow,coneshaped member open at its base end, an oppositely disposed frustoconical --shaped member arranged with its base end projecting into thebase end of said cone-shaped member and secured to same, and elongatedslots in the sides of said 'frusto-conicalshaped member, for the purposedescribed.

CARL J. MAGIN.
